Title (EN) EXHAUST GAS TREATMENT APPARATUS AND EXHAUST GAS TREATMENT METHOD
(FR) APPAREIL DE TRAITEMENT DE GAZ D'ÉCHAPPEMENT ET PROCÉDÉ DE TRAITEMENT DE GAZ D'ÉCHAPPEMENT
(JA) 排ガス処理装置及び排ガス処理方法
Abstract:
(EN) The exhaust gas treatment apparatus according to the present invention is provided with: an exhaust gas flow channel that is formed so as to allow NOx-containing exhaust gas to flow therethrough; and a first spray nozzle, wherein the first spray nozzle is provided with at least one spray hole for spraying cooling water into the exhaust gas flow channel so as to form first mist; and an ozone ejection port that is disposed so as to supply ozone gas to a local cooling region of the first mist at 150°C or less, wherein the at least one spray hole is characterized by being disposed so as to surround the ozone ejection port or an ozone gas flow channel through which ozone gas is supplied to the ozone ejection port.
(FR) La présente invention concerne un appareil de traitement de gaz d'échappement qui est pourvu : d'un canal d'écoulement de gaz d'échappement qui est formé de sorte à permettre à un gaz d'échappement contenant du NOx de s'écouler à travers ce dernier ; et d'une première buse de pulvérisation, la première buse de pulvérisation étant pourvue d'au moins un trou de pulvérisation destiné à pulvériser de l'eau de refroidissement dans le canal d'écoulement de gaz d'échappement de sorte à former un premier brouillard ; et d'un orifice d'éjection d'ozone qui est disposé de sorte à fournir de l'ozone gazeux à une région de refroidissement locale du premier brouillard à une température égale ou inférieure à 150 °C, le ou les trous de pulvérisation étant caractérisés en ce qu'ils sont disposés de sorte à entourer l'orifice d'éjection d'ozone ou un canal d'écoulement d'ozone gazeux à travers lequel de l'ozone gazeux est fourni à l'orifice d'éjection d'ozone.
(JA) 本発明の排ガス処理装置は、NOxを含む排ガスが流れるように設けられた排ガス流路と、第1噴霧ノズルとを備え、第1噴霧ノズルは、前記排ガス流路中に冷却水を噴霧し第1ミストを形成するように設けられた少なくとも1つの噴霧孔と、第1ミストの150℃以下の局所冷却域にオゾンガスを供給するように設けられたオゾン噴出口とを備え、少なくとも1つの噴霧孔は、前記オゾン噴出口にオゾンガスを供給するオゾンガス流路又は前記オゾン噴出口を囲むように配置されたことを特徴とする。
